    • An apparatus, system, and method are disclosed for managing storage space allocation. The apparatus includes a recognizing module, a reserving module, and a managing module. The recognizing module recognizes a trigger event at a client of the data storage system. The reserving module reserves logical units of space for data storage. The management module manages the logical units of space at the client. Such an arrangement provides for distributed management of storage space allocation within a storage area network (SAN). Facilitating client management of the logical units of space in this manner may reduce the number of required metadata transactions between the client and a metadata server and may increase performance of the SAN file system. Reducing metadata transactions effectively lowers network overhead, while increasing data throughput.
    • 公开了一种用于管理存储空间分配的装置,系统和方法。 该装置包括识别模块,预留模块和管理模块。 识别模块识别在数据存储系统的客户机处的触发事件。 预留模块保留数据存储空间的逻辑单位。 管理模块管理客户端的逻辑空间单位。 这种布置提供了对存储区域网络(SAN)内的存储空间分配的分布式管理。 以这种方式促进对逻辑空间的客户端管理可以减少客户端和元数据服务器之间所需的元数据事务的数量,并且可以提高SAN文件系统的性能。 减少元数据事务有效降低网络开销,同时提高数据吞吐量。

    • A method of passing data securely from an originator to a recipient comprises the steps of: the originator selecting a condition that the recipient must meet for receipt of the data; the originator selecting a trusted party; the originator selecting a first key without reference to the condition; the originator encrypting the data using the first key; the originator making the condition, and the encrypted data available to the recipient; the recipient providing the trusted party with evidence that it meets the condition; the trusted party satisfying itself that the recipient does meet the condition and providing the first key to the recipient, and the recipient decrypting the data using the first key.
    • 将数据从发起者传递到接收者的方法,包括以下步骤:发起者选择接收方必须满足以接收数据的条件; 创始人选择信任方; 始发者选择第一个密钥而不参考该条件; 发起者使用第一密钥加密数据; 作出条件的发起者,以及收件人可用的加密数据; 接受方向受信方提供符合条件的证据; 信任方满足接收者确实满足条件并向接收者提供第一密钥,并且接收方使用第一密钥来解密数据。
